The future network comprehensive report on the U.S. Quartz website November 23 said Google revealed and admitted that a part of the Android system users have been "monitoring." Google says it can still track users of Android even without networking, GPS or a lack of SIM cards.

Google has been collecting data from users since January 2017. The corresponding position location is determined by the distance from the nearest cellular data towers. This approach works even if you are shutting down geolocation services or if you are missing a SIM card.

Each time the smartphone goes to the next signal tower, it will automatically deliver information about its location to Google when it turns on Wi-Fi or GPS.

But Google said it would not save the user's data and intended to close the feature in the near future.
